Tanky Firebrand: Dire or Shaman/Settler?

Hi!

I want to build up for WvW and I'm and to be tanky to be able to be in front line. What Stat combination is better for Firebrand? Dire (COND/vit/Thoug) or Shaman (VIT/cond/healing)? Also would be good to mix Shaman with Settler?

It seems that is worth to take a bit of healing powerbecause the Tome of Resolve have a decent healing scale, it seems.

I'll mix up with a few Trailblazers because I'm will not taking Radiance most likely.

@editThere is Apothecary as well, I forgot about this stat.
